We used it at Main Street Bakery -- you could get any two items plus a drink. For DS and I we got 2 packages of grapes (very generously sized and packaged in a nice "squish proof" container), a bagel with cream cheese, a package of 2 donuts, and 2 large bottles of water. It was nice because we had plenty of food for 2 ( we each had 1/2 large bottle of water, 1/2 a bagel, a donut and some grapes each) plus a nice snack for midday (another 1/2 a bottle of water and some grapes).
Frankly we would have been fine with one meal (split a water, a bagel and some grapes), but because we did extra TS we had trouble using all of our CS's.
